The greatest challenge to helmet diving was

• losing divers in currents

• protecting divers from sharks

• regulating the temperature

• sustaining appropriate air pressure

Mixed-gas diving is typically used for

• dives in very cold water.

• dives in very warm water.

• extremely lengthy dives.

• extremely deep dives.

If divers enter and exit an underwater habitat through a “moon pool,” which of the following describes the air pressure in the habitat?

• Air pressure is equal to the outside water pressure.

• Air pressure is lower than the outside water pressure.

• Air pressure is greater than the outside water pressure.

• It is impossible to know based on this information.
